What's The Oldest Samsung Phone That Still Gets Software Support?

Key Points:

• One UI 9, based on Android 17, has been rolling out to supported Samsung phones since September 2026, with older flagships receiving the update in October, but devices predating the Galaxy S23 lineup will not get One UI 9 and will remain on One UI 8 with security updates until 2027.
• Samsung's seven-year update promise applies only to flagship phones released in 2024 or later, meaning the Galaxy S23 series is at the end of its upgrade cycle with One UI 9 as the last update.
• The Galaxy S24 series is the oldest flagship expected to receive software support beyond One UI 9, while select Galaxy A series models like the A16, A26, A36, and A56 will continue to be supported, but models such as the A15 and A25 5G will lose support by the end of 2027.
• Samsung distinguishes between major OS upgrades and years of security support, promising seven major updates and seven years of security independently, so users can track their device’s update status by counting received upgrades or following One UI beta cycles.
• Users interested in early access to updates can enroll in Samsung’s One UI beta programs via the Samsung Members app, but should back up data due to potential bugs in beta releases.
